摘　　要：为提升学生在通信系统方面的实践动手能力,设计开发了基于mini-LED的光无线通信实验平台,开展数字光信号调制、传输和解调的实践教学。该平台以mini-LED作为通信光源,包括自由空间和水下两种传输信道环境,在收发端以离线数字信号处理方式进行信道均衡和信号恢复。基于该实验平台,通过参与实验搭建、信道调试与数据分析,可帮助学生理解通信概念与理论,加强学生解决通信系统实际问题的能力,提升学生对光无线通信的系统设计与仿真实践能力。In order to improve students’ practical ability in communication systems, an optical wireless communication experimental platform based on the mini-LED is designed and developed to carry out practical teaching of digital optical signal modulation, transmission, and demodulation. The platform uses mini-LED as the communication light source, including free space and underwater transmission channel environments, and performs channel equalization and signal recovery at the transceiver end by offline digital signal processing. Based on the experimental platform, and by participating in experimental construction, channel debugging and data analysis, it can help students understand the concept and theory of communication, strengthen their ability to solve practical problems of communication system, and improve their ability to design and simulate optical wireless communication system.
